I've lived as an expat in Bangkok for a year and so for all people reading this considering to come - the location of Patty's place (in Condo Keyne next to Thong Lo BTS) is the very best location in Bangkok!!! By a mile. You're 30 seconds from BTS access to wherever you want to go - while also being in the Thong Lo area. Think of Thong Lo as Bangkok's upper east side, with all of the top restaurants, cafes, bars/clubs, etc. If you are a foodie/like a drink this is the best place to be!
Patty herself is a good host who is happy to help with tips for your stay. Very friendly and quick response time and some flexibility on check-in/check-out as no guest before/after. In a great stay the Only minor feedback I can think of is some of the furniture could be improved (e.g. couch and tv not great).
